This seemed like a good tactic to download and check out, but what really made me get it was the money back guarantee. :)
I'll post my findings after I give it a few spins.

I might also add that with further practice, I have found this to be an amazing tactic to use solely for big games (big league games, continental and cup comps), whilst used alongside a more low risk tactic which can be used during any other game. Using this for every game will work for around a season but can wear off in effectiveness as the AI "figure it out" as such.

@pgeorgiakos I had less success with IW - IF is very high risk high reward in the context of this tactic, the wingers are not always productive but they can be absolutely game changing when they need to be. However I am currently experimenting with basic wingers on attack and also playmaker wingers to see if this offers any greater consistency whilst minimising risk.

Can you use IW instead of IF?

Tested it with Eibar in LaLiga, was 3rd in first season with no signings, fine tactic but you need to get those wingers steady.
